SACRAMENTO — A suspected far-right extremist and radicalized supporter of former President Trump facing federal explosives charges may have been targeting California Gov. Gavin Newsom and the San Francisco Bay Area headquarters of social media giants Twitter and Facebook, according to the FBI. Federal prosecutors charged Ian Benjamin Rogers, 43, of Napa County, with possessing five homemade pipe bombs that investigators found when they searched his home and auto repair business Jan. 15. They also confiscated additional bomb-making material along with 49 firearms and thousands of rounds of ammunition. According to an FBI affidavit, Rogers made multiple threats in text messages to attack Democratic targets and ensure that Trump stayed in office.
